We recommend that the following conditions be made a part of the conditional use permit. A haul route and disposal location map. construction phasing schedule, and a traffic control plan must be submitted to the Cit>- for approval prior to commencing with the work. The written construction schedule must be updated or modified as necessarx' to accurately reflect the rate and progress on the project. .A pre-construction conference should be held with the MCWD, contractor. Cih-, Counw and other pardes involved in the project. The traffic control for the project should include a mlajmu.m of traffic control signs and dcvws contormme to the M.MUTCD. flagmen, a sueet sweeper, a sanding truck and a bobcat. The equipmenf wiil be necessarx- because it will be impossible to remove all mud from tires before leaving the site. The MC\\’D should be responsible for cleaning the surface of any paved public street that becomes soiled due to the construction activities on this project. When the MCV\T> constructed the Gleason Lake project in 1994. there were many problems associated with hauling on Highway 12. Depending on tlic haul route piopo^d. a letter of credit in an amount calculated bv the Citv* should be provided for potential damage to the local road system. This amount should be in addition to any rep.-xirs or oyerlav-s proposed bv the MCWT) For safct\' reasons, in times of inclement weather or early thaw, the Cit>* must have the auehoritv- to stop all hauling activin- until such tunc lh.it the Citv deienmiies necessaiy. The project specifications should be provided to the Citv- for clarification of details such as the following: what seeding mixture is proposed, will fertilizer be used, what is planned tor disposal of the cleared tree's? The plans do not appear to show any erosion control dunng construction, this should be addressed. The slopes just belovy the water line are shown at 61 (horizontal to vertical). The Citv tvpically requires iO:l slopes wh.ch will increase the amount of emergent vegetation and provnde an additional measure of safety, unless the area wUl be fenced. What will be the procedure for maintaining the ponds assuming that beavers 2335 West Highway 36 • St. Paul, MN 55113 • 612-636-4600
